Be iE known thaE I, GEORGE M. BRILL, of Ehe eiEy ancl eounty of Philadelphia, anal Stete of Pennsylvania, hzwe invented an Improve 1nenE in Oar-Trueks, of whieh Ehe following is a specifieation.

lllyinvention has reference Eo ear-Erueks; an(l it eonsisus in eertain improvemenbs Ehereon by whieh Ehe lower und eentral art of Ehe Eruck is lel'E eomparatively elear by Ehe usual hangers and eross-Eixnbers upon whiCh Ehe Springs 1GSECL1 heing eliminated, all of which 1's fully seE 1'012Eh in Ehe following specifieation anal shown in Ehe aeeompanying dmwings, whieh form pmE Ehereof.

In milway trueks, espeeially those for freighE-cars, Ehe bolster supporting Ehe Carhody rested upon springe whioh were placed upon a eross Ein1ber o1 beznn hung hy links from Ehe fm1ne 0f Ehe Eruek.
